113 reviews for Deep Blue Pro High strength Sodium Hypochlorite Patio cleaner 25L 25 Litres liquid chlorine for moss algae weeds bleach

  1. Carole Lalonde

    I have a patio sets that were laid around 3 years ago and cleaned last year with mild bleach a stiff broom. That took some time effort so this year I thought Id give this a go. I could see a significant difference the day after I applied the Deep Blue in a 61 mix, especially where I had only half finished some areas i.e. the dividing line was quite obvious. It had removed the green grey deposits, only leaving those areas on the slate that were pitted and so had gone quite black I double treated those areas today and await the results. So for me Im impressed with the cleaner. I picked up 5 litres in a sale for 12 and despite this being quite a lot more than cheap bleach and elbow grease, Ill be happy if thats all I need to do to it for this year. Time will tell of course. If I could figure out how to upload an image Id do so to show the difference between the area treated vs untreated…..

  2. Rebecca Hobbs

    At last, a patio cleaner worthy of the name. I have a Kota stone patio aka Indian slate or sandstone that was laid 20 years ago. Unfortunately, despite being regularly cleaned with a pressure washer, it had become disfigured by black spots caused by algae etc. Amazingly, a single application of this product, diluted 1 part to 4 parts water and applied using a pressure sprayer, has left my patio as clean as when it was first laid. Highly delighted with the result.

    Simple to use. Used on patio slabs

  12. sigrun philipps

    awesome

  13. Cristian Ferrazza

    Worked well on my slabs

  14. rosa maria ruiz cumbreo

    We have been using this stuff for about 3 years and I would say if you are only using it twice a year it will take that length of time to really become effective . We no longer have green lichen on our patio even after winter and the black spot mould we had has slowly been eradicated . The product is safe for pets once dried . Would advise buying a proper sprayer that you can strap on so you get even coverage .

  15. Mrs. Felicity Taylor

    This is much better and easier to use than the Karcher. I saw a big change in the look of our mouldy fence overnight. Tried it on mouldy trim on the car, sorted overnight. Now using on the patio and conservatory. Your imagination is the only limit.

  16. Muscle Ballers Ltd (verified owner)

    sprayed a small portion of neighbours rendered wall and amazed how it cleaned up in a few weeks

  17. Jennifer Flint

    purchase this product on recommendation of my son it work great on green algae on my paths and patio areas. would definitely recommend it for paths and fencing.

  22. Sandy E

    Diluted with 40 water and sprayed sparingly on to a patio, this cleans the slabs of mould and algae absolutely brilliantly like a new patio. But be careful not to get it on clothing, plants etc as its very alkalinecorrosive.

  23. Raymond Cox (verified owner)

    Amazing stuff thank you again

  24. Michelina I. (verified owner)

    I used the last of my previous product on part of my patio and had to wait for another suitable day to do the rest with this Deep Blue. Where Id used the other it had become clean showing up the rest, so the first thing I did was the rest of the patio before the other pavers.Four days later there were still dark marks right across, so Im very disappointed that it did not live up to its advertisement.

  25. SKA (verified owner)

    Not the best one that I have used

  26. RuthH

    Amazing stuff

  27. Janicef

    Parts of our roof, guttering and patio were covered quite extensively with moss. A fairly light spraying killed it within two days.

  28. Scott M.

    This product is fantastic. We have a natural stone patio and pathway and have used this twice now. We wash the patio clean first with cold water and fairy liquid and a stiff broom. Allow it to dry. Apply this product as a protective layer which just keeps on working.

  29. Robert A. Chalmers (verified owner)

    I love this stuff, was amazed how it gradually lifted the colour of my patio, I didnt realize my paving slabs were beige I had always thought they were grey. I think with this product patience is the key, algae and moss disappears quite quickly but took up to 6 months to lift the actual colour of the slabs. However I wasnt expexting such a dramatic change and it was well worth the wait. It does tend to leave rust type stains on some surfaces so do a test patch first

  30. Marie gear

    Treated my balcony which hadnt been treated for 3 years because of Ill health. It cleaned the green really effectively. Easy to make up. No horrible smell I painted it on with a large paintbrush and after 4 hours the green was gone so pleased. I would recommend this product particularly if like me you cannot use a spray to apply the product because I live on the first floor and have neighbours with a patio below my balcony.

  31. Cognitive Economy (verified owner)

    worth the money

  32. Brian Faulkner

    I was sceptical, having tried many products in my annual patio spring clean, and concluding that the pressure washer in the end does the job but after reading the reviews, I am really glad I gave it a try.IT WORKS AS DESCRIBED much better than anything I have tried before. Make sure to follow the instructions, and be patient it takes several days to see the results, but it really works After leaving it for about a week and noticing some brightening, the black mould and dirt washed off much easier than ever before and my patio has never looked better since new 11 years ago.I also sprayed some of the leftover mix on part of my red brick driveway, and without any washing I can see this part much cleaner and lighter now so it does work on its own too.Excellent product

  33. Joachim Z.

    After this there are no patches of green and my patio looks as good as day when fitted

  34. John Milton

    Deep Blue is an amazing product.Very easy to dilute and apply, it doesnt work its magic over night, but in time it brings your patio slabs back to new.More importantly it keeps them looking great for ages.Previously I had power washed the slabs, they looked good initially but not as good as using Deep Blue and didnt last as long

Ive used it on the drive, the patio, the patio wall, the fence as gone green. Now going to use on the conservatory roof as it will get rid of the moss, if I could reach the roof with it then that would be next…. Amazing stuff thank you again..

  51. jml1712 (verified owner)

    Simply remarkable effects. Mixed up as per packaging and applied to our sandstone paved patio which had gone an unpleasant shade of green. A few days later the slabs look as good as new. No algae growth and a lovely grey colour again. Its even killed the moss that was attempting to grow in places too. Quick to apply and really does work

  52. Lynn Taylor (verified owner)

    This stuff is amazing. My algaestained, dull and grubby limestone patio flags came up almost as new. I must admit I was surprised. Like other have said, it took a few weeks but it was worth the wait. Several months on, they are still light and clean. Next year, Ill get some more for my drive.

  53. blag (verified owner)

    Used this to remove blackspot from the rear patio. Power washed the whole area first to get rid of the last years grime, then sprayed the Sodium Hypochlorite at a 5050 water ratio on approx 3sq yards at a time, left it for 30 min and washed off, excellent result. Then repeated over whole patio at similar sized areas and could not fault it. Have only used about 8 of the 20 litres that I ordered so will be ready for next year, if the blackspot returnsTBH I think I could have done the whole patio in one go and not waited the 30 min however the problem of continually shifting garden furniture pots and plants made that a tad impractical.Dont have a before after image but this shows how clean it is, almost like new

  54. Rabbi Yaakov Schweitzet

    I was expecting nothing to happen after reading reviews on this product, however within 24 hours the whole patio was completely clear, all of the green algae had evaporated, it just needs sealed now.

  55. Sir Osis of Liver

    Great stuff, patio and boat decks

  56. hayley brodericktaylor

    Well I dont know how it works but it does. Not very much happens overnight on the patio slabs and wall but each day they became cleaner. Very easy to use. Just spray the areas you want to clean and leave.

  57. Paula Vurlan

    So easy to use, it say spray on, but I made the mixture up in an old kitchen bowl and used a sweeping brush to brush it on, I did about 50 sq mtr in no time and still had a bit left from the 2.5ltr. 2 weeks in and you can see the difference, the patio is a lot lighter.I usually jet wash my patio, to do the same surface area would take me about 56 hours, and loads of water and hard work, with wet and forget I had it done in less than 2 hours, hardly any water and the same amount of arm work. It is also less messy.We just kept the dog away until it was dry hes been fine.

  58. Herv le Hibou

    Spent quite a lot of money on new light coloured patio 2 years ago. Being surrounded by conifers I have watched my patio slowly turning green over this winter. Having heard horror stories about using pressure washers on patios I thought Id look for something less aggressive. When I saw the pictures on the front of the container I was sceptical. In the spring I sprayed it with Deep Blue. It really worked, there were a couple of areas that had to be sprayed a couple of times. After this there are no patches of green and my patio looks as good as day when fitted. My patio is approx. 40m2 and I used 12 bottle after 2 winters. Would highly recommend.

    Used WetForget to clean brick pave driveway natural stone patio. Easy to make up solution but you need to make up a device for your hand held garden sprayer to make the handle longer as the weight of the bottle leaning over is tough on your back. Does a great job but you must be patient it may take a couple of weeks before you see a difference as it works with rainwater. Very pleased with this product

  71. John Perham

    followed the instructions and used a light brush to spread the liquid. The indian stone started to turn light brown so got the hose pipe on it straight away. When it dried the brown stains were there and the original marks still there with no improvement. Sorry we tried this on our 4year old indian stone patio.

  72. notestein

    Excellent product. It works really well on patios etc. Anyone want to purchase a pressure washer

    It does get ride of the moss and green tinges, but you still need to properly clean the patiodriveway with a jet wash.

    Does what it says on the bottle.

  76. Jov

    Got most of the Algae off the patio

  77. b v

    I used this product to clean my patio which is made of Indian stone and also my driveway which is PlasPave block paving. I applied it while the slabs were completely dry and no rain was expected for at least 8 hours. There was soiling everywhere but not heavy. I mixed it at a four to one ratio of water to cleaner and applied it with a watering can and saturated the area. I scrubbed it gently with a brush while applying it even though the instructions state that you dont have to. I just wanted to make sure that it went into the crevices ok.Within an hour of it drying you could see that the green had gone and at that point the patio looked massively better but just a bit dirty.48 hours later and the patio looks first class and Ive done nothing else to it. It has almost rejuvenated itself. The dirt has just gone.Like many I was dubious about a product such as this with regard to the claims but hats off to the makers because it is a fantastic product. Just follow the instructions and it will work just fine. It is non acid so it isnt eating into anything and I certainly have no desire to return to the days of jet washing which I used to with my other Yorkstone patio because although the jet washing made it look ok for a while afterwards the colour was being sucked out of the slabs and more small holes were being blasted into the surface to allow the mould and algae to quickly return. Another huge bonus with this product is that youre not blasting away at the grouting or cement in between the paving. A damn sight easier and quicker than jet washing as wellJust be careful that the solution doesnt come into contact with any grass or plants and if if you have pets wait until the surface is completely dry before letting them out on to it.An excellent product that far exceeded my expectations and does what it says on the container.

  78. sharon mundie scott (verified owner)

    Whats not to like. Mix it up, spray it on and walk away. Whilst pressure washing the patio may be satisfying, it does produce a lot of mess, with this there is none and it keeps working to make your slabs sparkle all year.

  79. tvulker

    this really works. it has cleared up my filthy patio, and i have a lot of patio. it took time maybe a few months. the recent nonstop rain in the UK has helped, and they are now very, very clean. not perfect but so much better.has saved me a fortune on getting someone in, and a weeks of toil had i decided to rent a water blaster and do it myself.effect lasts too.i also use this on the window and door frames and garden furniture. same result, invisible magical protection.

  80. SusanPoppins (verified owner)

    I have always used Deep Blue fluid for cleaning our outdoor bins and also our garden patio. Awesome product

  81. marianna (verified owner)

    easy to use and the results are the envy of every one my patio has never looked so good

  82. Narkoslkare (verified owner)

    Bought this after reading a mix of reviews. Mixed 2.5 litres of product to 20 litres of water. Then went after my unsightly and slimy blue green algae, blitzing all in my path, my fence , patio, kerb stones, render base brickwork and hoped for the best. Next day, the blue green mess was dead and I swept this up with ease, mainly as I like things tidy and presentable. There is also a remission of moss build up on my wooden fence and brickwork. Love this product, and will be buying more to store, should the problem rear its head once more. No brained purchase.

  83. Christina Strasser (verified owner)

    Best patio cleaner Ive ever used.

  84. Tim Corbett (verified owner)

    I was recommended this Patio Cleaner. Perhaps my patio was very bad but it didnt clean it particularly well. After washing it on you have to wait 34 days before you can see an improvement. Certainly got the worse off but had to jet wash after to clean completely.

  85. Michael Tracey

    I used this to kill black lichen stains and my garden paths and patio. I diluted 3 to 1 and it worked vey well. I had been using Lithofin, which is about the same price for 1L and its only a 5 solution. ie., this is only 115th of the Lithofin price. To be fair, since this stuff is very strong and potentially dangerous, I had to buy protective clothing gloves and goggles but they cost less than 10 so I am still much better off financially.Decanting to a smaller container was pretty messy the first few times but became easier when the container was not so full. Its certainly true that its more hassle to deal with than Lithofin, and there was definitely some spillage, but it is well worth it.Addendum I went to use the stuff Id bought a year or so earlier and discovered it had gone off. There was not even a trace of the chlorine smell and it was totally useless. Apparently this is a fact of life, not a product defect, so , the lesson is to only buy what you need for immediate use. Even if, like me, you onlyy use half the container, its still a bargain.

  86. Elizabeth Prole

    I used this on my patio and block drive. It has cleaned them and also killed some little weeds

  87. Rebecca Laupichler

    This product is brilliant I borrowed some of this from my friend who recently purchased some and now swears by it. I cant believe the difference its made to my patio It looks like brand new. I will definitely be recommending this and using it again if needs be.

  88. christopher sitzmann (verified owner)

    I had a rendered exterior wall which was becoming quite stained. One spray of Deep Blue and some brushing has returned it to its original state. It has also eradicated the liverwort which used to appear between slabs on my patio and dealt with green discolouration on the window seals of my car. Treatments on exterior stonework paths need to be repeated about every couple of months but the product dilutes 15 and lasts well.

  89. Craig Lowe

    Great on decking, canopy and green patios, fences, polytunnels….For really green areas dont dilute the wet and forget too much. There is not much point using wet and forget if it is going to rain. This works best in the summer. But generally green comes up in the winter, so check for a window of at least 24 hours with no rain.

    It seems to be working really well the more time goes on the cleaner the stones become. Ive even done my neighbours.So easy to apply and its not damaging the filler in between which jet washing was.Itll be a test over winter if our patio doesnt go green. Picture is of tarmac drive and wall half done so you can see the difference.It really is like magic so glad I was recommended to buy this. Next spring Ill be wet and forgetting everything

  112. Leo GB

    This patio cleaner is amazing, mix it with water and swill it onto your patio. My yard grows green slime mould every year throughout winter. One tub of this and it looks like the yard has been jet washed. As an added bonus it kills all the weeds that grow through the cracks in the flags. Great product.

  113. R. George

    Weve used this for years. It was formerly marketed as BRINTONS but they seem to now be putting the emphasis on Deep Blue.Our house is surrounded by steps and York stone paving slabs, which become lethal as a thin layer of algae builds up on them and with the slightest sprinkling of rain turns them into a skating rink. One way of dealing with this might be pressure hosing, but in time that blasts out the mortar and weeds flourish, so I use Deep Blue which really kills off the algae and gradually also returns darked stone slabs to their original colour. Excellent product and we got it at an excellent price on Deep Blue, together with fast delivery. Well done all round.
